    Expression f.getFiles(project) is a method call throwing exception(s) that should be caught by a try block that will be extracted
    Expression p1.getExcludePatterns(project) cannot be parameterized, because it has dependencies to/from statements that will be extracted

    Expression p1.getExcludePatterns(project) is a void method call, and thus it cannot be parameterized
    Expression f cannot be unified with expression p1 , because common superclass org.apache.tools.ant.types.DataType does not declare member(s) public java.lang.String[] getFiles(org.apache.tools.ant.Project) , public java.lang.String[] getExcludePatterns(org.apache.tools.ant.Project)
